Description
前記吸収体は、下層吸収体と上層吸収体とから構成され、少なくとも排血口対応位置及びその近傍において、前記下層吸収体は、展開状態の横断面形状が略水平な底面と、底面の両側縁部から斜め外方に立ち上がる側面と、該側面の頂部から上面中央に形成された最薄部に向かう傾斜面によって略V字状の谷溝を有する断面形状を成し、前記上層吸収体は、展開状態の横断面形状が前記下層吸収体の上面に形成された略V字状の谷溝を埋めるように略逆三角形状の断面形状を成し、
前記上層吸収体の表面より前記下層吸収体の両側部に形成された頂部の方が高く形成され、身体への装着状態時に前記頂部が鼠径部を埋めるように身体に当接することを特徴とする吸収性物品が提供される。
前記不透液性裏面シート2は、ポリエチレン等の少なくとも遮水性を有するシート材が用いられるが、近年はムレ防止の観点から透湿性を有するものが用いられる傾向にある。この遮水・透湿性シート材としては、ポリエチレンやポリプロピレン等のオレフィン系樹脂中に無機充填剤を溶融混練してシートを成形した後、一軸または二軸方向に延伸することにより得られる微多孔性シートが好適に用いられる。
Claims (5)
- 透液性表面シートと不透液性裏面シートとの間に吸収体が介在された吸収性物品において、
前記吸収体は、下層吸収体と上層吸収体とから構成され、少なくとも排血口対応位置及びその近傍において、前記下層吸収体は、展開状態の横断面形状が略水平な底面と、底面の両側縁部から斜め外方に立ち上がる側面と、該側面の頂部から上面中央に形成された最薄部に向かう傾斜面によって略V字状の谷溝を有する断面形状を成し、前記上層吸収体は、展開状態の横断面形状が前記下層吸収体の上面に形成された略V字状の谷溝を埋めるように略逆三角形状の断面形状を成し、
前記上層吸収体の表面より前記下層吸収体の両側部に形成された頂部の方が高く形成され、身体への装着状態時に前記頂部が鼠径部を埋めるように身体に当接することを特徴とする吸収性物品。 - 前記下層吸収体は、少なくとも排血口対応位置及びその近傍において、前記谷溝の最薄部に、長手方向に沿ってエンボスを付与してある請求項1記載の吸収性物品。
- 前記下層吸収体は、少なくとも排血口対応位置及びその近傍であって、上層吸収体側縁よりも外側の前記頂部を含む吸収体部分において、高吸水性樹脂が他の領域よりも含有量が多くなるように偏在して混入されている請求項1〜2いずれかに記載の吸収性物品。
- 前記下層吸収体の両側面及び底面の外側を覆うように、防水シートが配設されている請求項1〜3いずれかに記載の吸収性物品。
- 前記下層吸収体の両側面を覆うように、先端部が外側に向けて延在する立体ギャザーが配設されている請求項1〜4いずれかに記載の吸収性物品。
